[RMMV] GAME FREEZE ON STARTUP

Okay. So my game has this nasty habit of freezing on startup. You load the compiled EXE and get "Now Loading...", except that it's not loading anything, and it doesn't spit out any meaningful error messages.

This happens consistently for some playtesters, and at a rate of about 1 in 5 startups for me. This occurs regardless of whether the assets are encrypted or not. I've also tried turning off the most recently added plugins, as it's a new-ish problem, but no improvement.

Anybody else encounter this and solve it in the past? Is there a way I can test for the cause of this problem? It doesn't occur in playtesting from MV directly, so the inbuilt console isn't going to be of much help.

Also, compiling an EXE from the HTML5 output using an alternate method fixes this problem, but creates another; savegames are only valid for the length of any one session, being deleted the moment you close the game. The fact that the game will run without freezing at startup however, using an alternate compiler, seems to indicate that the problem is with the way MV compiles its EXEs, not with the game assets or anything like that. Don't know for sure though, which is why I'm asking...
